Specification. of Letters Patent. Application manages; .10, 1911. Seria1No. M3358.-

To all whomit may concern:

Be it known that I, CHARLES S. LooK- woon, a citizen of the United States, residing at 289 Market street, Newark, county 5 of Essex andState of New Jersey, have mvented certain new and useful Improve ments in Collared. spirally-Wound Rolls, fully described and represented in the folit lowing specification and the accompanying 10 drawings, forming a part of the same.

This invention isa'a modificationof that patented to me: April 26, 1910 with No.

955,888 for a roller bearing with combined thrust and bearing rolls, and the invention consists in'making the rolls with a spirally wound body and an integral collar upon the same; but the. present invention is applicable to other bearings. -.In the. said patent, two sets of conical rolls were shown fitted to opposed conical roll-seats and having collars upon their largerends'to rotate in contact with one another in a-groove formed at the junction of the seats. Such rolls have heretofore alwaysbeen made solid, and the object of the present iIlVQIltlOIl is to secure in such a construction the advantages of a spirally wound roll which possesses far.

greater elasticitythan a solid roll,

A's spirally wound rolls are formed of a strip of uniform thickness, no attempt has I heretofore been made to use them. in con: structions where a' collar. upon the end. .of the roll was required, as roll formed of a spirally merely a continuous straight surface, and .the roll cannot-be enlarged inwinding to form a collar thereon. I have devised a means of providing such a roll with a col-- lar, which consists in forming the roll primarily from a stri much thicker than i's required I for the p the roll externall for the greater part of its length after the rollis wound, leaving a collar of the desired proportions at any 'reitself is thus an integral attachment ofthe coils which form the roll and shares in the elasticity of the roll-body, which in its final erence to the annexed drawing, in which- Figureil is a longitudinal section, .where xhatch'ed, of abearing having the spirally 85 wound rollswith loose washers ad omlng the surface of a.

I 62- represents the hub oft he bearing havadjoining and separated by a groove 0 having shoulders c at its opposite ends formed at right angles to the surfaces of the conical seats. The external casing d is shown with conical seats and e, and the conical rolls f are fitted between the seats of the hub and lug conical seats I) and b? with their bases the casing, with collar 9 extendinginto the groove 0. 1

The roll, as shown in Fig. 3,, is primarily formedby winding upon a suitable man- -drel a\ strip of suflicientthickness to make the primary roll g" of the: diameter required for the collar 9. The roll-is then turned down, as show'n'in Fig. 4, to form the tapering body, end of the same. 'Theformin of the roll from 'a strip produces aspira division 71.

between the several coils, and such'division also intersects the collar obliquely.

The rolls are in practice held opposite to one another in pairs by. suitable openings in the ca e h," and the collars upon the rolls may t us be held with their outer opposed sides in contact, being formed with a suitable bevel'z' to increase the contact surface.

'. The inner faoesof the collars'are designed to react 'against'tho shoulders a when theleaving the collar 9 at one hub or casmglof the. bearing is subjected to e ndthrust; as the thrust is transmitted from one set of rolls to .theother, the collars thus preventing any displacement of the rolls upon their seats.

As the spiral division which intersects the collar forms'a joint in thecollar with a thin beveled'edge upon one side of such joint, it is undesirable to have such joint rotate in direct contact with the shoulder c.;and a washer j'is therefore shown ap 'liedto" the body of the roll between the co lar and the '10 v with a counterbore o, as shown in Fig.

shoulder c, to sustain the wear against the shoulder. 'Such washer may be made to turn loosely adjoining the collar 9 or it may be fitted tightly to the body of the roll so'as to turn therewith.

h Wherethe collars contact at their outer' sides, as in Fig. 1, there is some tendency to "loosen. OrQdi PIace the thin end of the coil which forms the collar g, and such tendency is readily corrected by forming. the washer 0 so as to'embrace the'periphery of the collar 9' and thus prevent any d1splacement or distortion of thecoil which forms the collar.

Such washer is not essential where the bear ing is not subjected to serious end strain,

and where the collars g are required only to hold the rolls in place under direct lateralv strain. "In such cases, the groovec-is, of

course, made of suitable width to receive 7 the collars andhave them contact directly with the shoulders 0'.

The hub shown" in Fig. 7 is formed with cylindrical seats is. at its ends and a groove 1 at the-middle of its length, and the rolls m are made cylindrical and formed with a collar n at. the middle of'the length with wash 'ers' at both sides fitted to the groove Z. Such rolls are made in the same mannerv asthe conical'rolls .of Fig: 1, by first forming a than the collar.- The spirally formed body possesses great elasticity, and-the bearings provided with such rolls thus support the load with less shock and jar, as in automo-' bile wheels. The parts carried by the bearings are thus jarred much less fviolently than if sustained upon solid rolls, and the durability of the bearing andof the parts carried thereby is greatly Increased. The application of the washers to protect the sides of the roll-collars which wear against the hub, secures the samedurability as a solid roll and collar would possess. The washers can also be cheaply renewed, when worn, as they form a'very cheap and simple element of the construction.

1 Having thus set forth the nature of the invention what is claimed herein is:

, L In a roller bearing, a roll formed of a spirally wound strand with integral collar thereon,the division between the strands extending through the said collar. 1 2. In a roller bearing, a roll formed of Hiral coils with integral collar thereon, and

s t e divisionbetween the coils extending through the said collar, and a' washer applied to the body of the roll adjoining such collar to cover the division joint.

'31 In a roller bearing, the combination, with a-suitable casing, of spirally wound rolls fitted to' such casing and having an in-.

tegral' cbllar thereon, and a hub having a seat fitted to the rolls and an annular s'houl deradapted to engage the said collar.

4.]In a' roller bearing, the combination,

with'a suitable casing, of spirally wound r'olls fitted to such casing and having an integral collar thereon, with washer fitted to the roll adjoining the collar, and a hub having a seat fitted to the rolls and an annular shoulder adapted to engage the said washer. .5.- In a .roller bearing, the combination,

with a hub having opposed conical roll-seats with a groove at their junction forming shoulders at the bases of the seats, of spirally wound conical rolls having. integral collars with beveled ends in contact in the said groove and the inner facesof'the collars opposed to the said shoulders.

'6. In a rollerbearing, the combination,'.

with a hub having opposed conical roll-seats with a groove at their junction forming shoulders at the bases of'the seats, of spirally wound conical rolls having integral collars with beveled ends in contact in the said groove and the inner faces ofthe collars opposed to the said shoulders, and provided with washers to contact with the said shoulders. w I y In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. 1 a I 7 CHARLES S.
